One of the core contributions of a DGGS is
geospatial data fusion on demand. In a multiple
provider environment, fusion is only possible
with an information system architecture based
upon open standards. The OGC DGGS Abstract
Specification provides a platform to enable
interoperability within and between different
DGGS implementations while promoting
reusability, knowledge exchange, and choices in
the design of individual DGGS implementations.
